摘要
Differential scanning calorimetry (DSC) was used to study the binary systems of C-60-o-xylene and C-70-o-xylene and the ternary system C-60-C-70-o-xylene. Fullerene C-60 formed solvated crystals C-60.2C(8)H(10) with incongruent melting point 320 K and with enthalpy of decomposition 31+/-3 kJ (mol of C-60)(-1). Two solvated crystals of C-70 with incongruent melting points 283 and 369 K, and with decomposition enthalpies 18.5+/-2.2 and 23.0+/-1.5 kJ (mol of C-70)(-1), were formed from o-xylene solutions. Three ternary compositions with C-60/C-70 mole ratios of 3:1, 1:1 and 1:3 were scanned by DSC.
